First drama I have started and my favourite, also I rewatched I think 4 times. OST is so freaking good, Breaking down is a masterpiece. Park Bo Young's acting just wow, Seo In Guk amazing, their chemistry together - there's no other their role partners where I like their chemistry as much - I really need next drama with this two as a couple. All actors did amazing job. Also love triangle for second leads was well done. Storyline was perfect, I cry everytime I watch this drama and I am so happy with the ending - I know that many people would like different ending and to be honest I would still love this drama exactly the same. I always recommend this when people ask about something to watch.
